TRANSPARENT PLANT PROTECTIVE COVER Filed Jan. 2, 1948 Inventor Pele? Jnes Attorneys Patented Aug. 14, 1951 UNITED STATES PATENT OFFICE Application January 2, 1948, Serial No. 46 In Great Britain January 6, 1947 4 Claims.

In a co-pending application Serial No. 662,821, now abandoned, are described spring clips for cloches of various types.

The present invention utilizes a clip of the same general type and a ridge member upon inclined side surfaces of which the glasses will lie when assembled and so engaged by the clip, at or near the crossing point of the limbs of the clip, that release of the clip when assembling the cloche brings the limbs down onto the glasses near the ridge, so gripping them against the side surfaces of the ridge member.

For this purpose the ridge member will preferably be formed of a metal stamping with a vertical ridge portion adapted to lie between the upper edges of the glasses (and engaged by the clip) and two inclined wings presenting side surfaces upon which the glasses will lie and against which they will be gripped as the angle at the ridge between the limbs becomes smaller upon release of the clip to close and grip the assembly.

The above and other parts of the invention are embodied in a typical form illustrated by the accompanying drawings. The parts for which patent protection is desired are those delimited by the claims.

In the drawings:

Fig. l is a vertical sectional view showing a simple cloche assembled, and

Fig. 2 is a similar fragmentary view showing the loop of the spring compressed, leaving room for the glasses to be readily inserted or withdrawn.

The spring clip shown is of simple form described in U. S. Serial No. 662,821, now abandoned, comprising a length of resilient material formed into a spring loop I with limbs 2 that cross one another, so that pressure of the limbs towards one another above their intersection at 3 eases the grip and provided with engaging means extending longitudinally at 4 to engage and support the lower edges of the glass sheets 5. The ridge member is formed from a piece of sheet metal doubled upon itself to form the vertical portion 6 and then bent outwardly in each direction at the required incline as at I, the lower edges of the inclines thus formed being preferably rounded in at the bottom to avoid a sharp edge. A suitable hole or aperture 8 in the vertical portion embraces the limbs at the crossing point, leaving room to insert the glasses when the spring loop of the clip is compressed, as shown at Fig. 2, but ensuring that they are nicely gripped by the limbs when the clip is released, as shown at Fig. 1.

The exact shape and material of the ridge member may be varied considerably within the underlying idea of the release of the clip causing the limbs (with or without interposed pieces) to press the glasses against it: it might for example consist of a wooden length presenting the desired inclines and fitted with an upstanding eye to embrace the limbs of the clip at their crossing point.

I claim:

1. In a cloche, the combination of a clip and a ridge member, said clip comprising bent limbs having their upper ends joined by a spring loop and hooks on their lower ends to engage panes of glass, said limbs intersecting each other so that pressure exerted on the limbs towards each other above their intersection eases their grip upon said panes, said ridge member having an aperture through which said limbs extend at their intersection, thus suspending the ridge member on said limbs and causing the upper edge portions of said panes to be gripped between the limbs and the ridge member when said pressure on the limbs is withdrawn.

2. In a cloche as set forth in claim 1, wherein said ridge member has downwardly diverging portions which contactthe upper edge portions of said panes flatwise.

3. In a cloche as set forth in claim 1, wherein said ridge member comprises a vertical portion and downwardly diverging portions integral with each other, the vertical portion having said aperture through which the limbs extend, and the diverging portions contacting the upper edge portions of said panes flatwise.

4. In a cloche, the combination of a clip comprising bent limbs having their upper ends connected by a spring loop and hooks on their lower ends to engage panes of glass, said limbs intersecting each other so that pressure exerted on the limbs towards each other above their intersection eases their grip upon said panes, and a ridge member through which said limbs extend at said intersection so that said limbs cooperatewith the ridge member to clamp said panes when said pressure on the limbs is withdrawn.
